TI  - Analysis of aerobic granular sludge formation based on grey system theory.
PG  - 710-6
AB  - Based on grey entropy analysis, the relational grade of operational parameters 
      with aerobic granular sludge's granulation indicators was studied. The former 
      consisted of settling time (ST), aeration time (AT), superficial gas velocity 
      (SGV), height/diameter (H/D) ratio and organic loading rates (OLR), the latter 
      included sludge volume index (SVI) and set-up time. The calculated result showed 
      that for SVI and set-up time, the influence orders and the corresponding grey 
      entropy relational grades (GERG) were: SGV (0.9935) > AT (0.9921) > OLR (0.9894) 
      > ST (0.9876) > H/D (0.9857) and SGV (0.9928) > H/D (0.9914) > AT (0.9909) > OLR 
      (0.9897) > ST (0.9878). The chosen parameters were all key impact factors as each 
      GERG was larger than 0.98. SGV played an important role in improving SVI 
      transformation and facilitating the set-up process. The influence of ST on SVI 
      and set-up time was relatively low due to its dual functions. SVI transformation 
      and rapid set-up demanded different optimal H/D ratio scopes (10-20 and 16-20). 
      Meanwhile, different functions could be obtained through adjusting certain 
      factors' scope.
